Trouble constructing an object and putting it into ArrayList

Question

I've created an ArrayList for objects of type ProductInfo, however NetBeans is telling me that on line 256 it can't find the symbol: method ProductInfo(int, int, String, String).

Here is the code code:

/**
 * Creates new form mVentoryHome
 */
public mVentoryHome() {
    initComponents();

 }

    public class ProductInfo{
    String name, des;
    int ID, num;

}

    /**
 *
 */
public static void Inventory(){

    }


//creat Array
    ArrayList <ProductInfo> Inventory = new ArrayList <ProductInfo> ();

/**
 * This method is called from within the constructor to initialize the form.
 * WARNING: Do NOT modify this code. The content of this method is always
 * regenerated by the Form Editor.

Define the constructor you are using on line 256:

public class ProductInfo{
    String name; 
    String des; 
    int ID; 
    int num; 

    public ProductInfo(String name, String des, int ID, int num){
      this.name = name;
      this.des = des;
      this.ID = ID;
      this.num = num;
    }
}

use new operator:

Inventory.add(new ProductInfo(Name, Description, Identification, Number));

I added the new code, and now it says it can't fin the variable 'name' in: "this.name = name;"

Alex Shesterov Over a year ago

of course you must not leave out the code you already had in the ProductInfo class. I've updated the answer.

Thank you so much @Alex! For the first time in months I have no red exclamation marks!
